Sucrose
A disaccharide that consists of 1 ring of glucose and 1 ring of fructose. It is processed from cane and beet sugar.
Lactose
A disaccharide that consists of 1 ring of glucose and 1 ring of galactose. When milk ___________ is digested - an enzyme (lactase) splits this disaccharide into two monosaccharide rings. Once split apart - these tow monosaccharides can be easily digested.
Maltose
A disaccharide that consists of 2 rings of glucose. It is a component of "malt", a product that comes from grain to soften and germinate in water. It is found in beer and commonly found in processed foods that have been sweetened including cereals and pasta.
quickly, glucose
A key issue is how _________ carbs are digested and converted into _______
Galactose
A monosaccharide that is also known as "milk sugar" is the least sweet sugar. It is found in dairy products. It comes from the digestion of milk sugar (When a molecule of ____________ is combined with a molecule of glucose, the result is a double sugar called lactose)
Glucose
A monosaccharide that is the body's primary source of energy. It is not found in food but it is derived from the breakdown of dietary starch, fructose, and galactose. It is in processed foods and part of milk. Sometimes referred to as dextrose
Fructose
A monosaccharide that is the sweetest sugar. It is most commonly found in fruit. The riper the fruit, the more ___________ it will contain. It is found in honey and some root veggies. ex. High __________ corn syrup
Starch
A polysaccharide that is the most common carbohydrate consumed and they are the key ingredients in food staples including grains, potatoes, rice, corn, and legumes (beans - seeds of the plant). It is produced by green plants to store energy. It is the primary source of energy for the body once it is converted into glucose.
High Fructose Corn Syrup
A sweetener made by processing the starch found in corn into fructose. Taking the starch in corn and converting it into sugar (fructose). It is cheap, liquid, and easy to store
glucose

Sun, plants
All energy comes from the _______. We need __________ to capture it.
Complex Carbohydrates
Also known as polysaccharides since they contain MANY chains of simple sugars. It provides the most health benefits + nutrients such as vitamins, minerals, and fiber. Foods such as bread, legumes, rice, pasta, and starchy vegetables contain complex carbohydrates Foods in this category are further divided into starches and dietary fiber. Starches & Gloycogen - Potatoes; Vegetables (amylose & amylopectin) Fiber 1) Insoluble (ex. Bran) 2) Soluble (ex. Oatmeal)
Simple Carbohydrates
Also referred to as "sugars" (or saccharides) are further divided into 3 forms of single sugars (mono-saccharides) and 3 forms of double sugars (di-saccharides) Simple Carbs --Mono-saccharides (1 sugar) 1) Glucose 2) Fructose 3) Galactose --Disaccharides (2 sugars) 1) Sucrose 2) Maltose 3) Lactose
Complex Carbohydrates
Also referred to as polysaccharides, as it contains MANY (poly) singular sugar units. These sugars are large and complex and ar further divided into STARCH, GLYCOGEN & FIBER
Carbohydrate
Chains of carbon that are fully hydrated with water (H2O). Composed of carbon, hydrogen, and oxygen atoms (CHO) - which make up the building blocks for a sugar, Or saccharide molecule.
Roots, stems
Common storage sites for plant starches: 1) _______ like Sweet Potatoes 2) Underground _________ like White Potatoes 3) Fruits like Winter Squashes 4) Seeds like Beans and Grains

Disaccharides
Part of simple carbohydrates and are double sugars (2 sugars) that are: 1) Sucrose 2) Maltose 3) Lactose
Endosperm
Part of the whole grain that contains the majority of starch (and protein). It is protected by outer layers.
Germ
Part of the whole grain that is the plant's seed since it contains the genetic material for a new plant. Also called the embryo. Also provides heathy oils, proteins. and fats
Bran
Part of the whole grain that is the primary source of fiber. It is the protective outer layer of the shell - it is high in fiber and B vitamins.
lactose intolerant
People who are _________ _______________ lack the lactase enzyme needed to split this disaccharide into 2 monosaccharides. But they can use bacteria to digest ________. In doing so, the bacteria produces large amounts of methane gas. But if lactose is not digested - it can result in osmotic diaherra and discomfort.
Amylose
Plant starch digested much slower and for that reason is the healthier starch
Amylopectin
Plant starch that is digested faster since digestive enzymes have more to work with -- but in this case, it's not healthy since when we digest things faster, still are hungry and not yet satiated

When it comes to determining how quickly a starch contains in grains is digested (and consequently how quickly our blood sugar rises) depends to a large degree upon how much the grain has been ____________
glucose, acid, CO2
When our bodies have adequate oxygen (aerobic conditions) in a process known as the Krebs cycle, ___________ is metabolized producing pyruvic ______ - which is then converted into Adenosine TriPhosphate or ATP. Under aerobic conditions, this process also produces _______ as a waste product - which we exhale
separates, slower
When sucrose is digested, the fructose ring _____________ from the glucose and then the fructose travels to the liver, where is its slowly converted into glucose and then slowly released into the blood. For this reason, sucrose actually elevates blood sugar levels ___________ than other foods - such as highly processed carbs found in white bread and junk food. So WHY is sucrose slower? because the fructose ring splits from the glucose ring and takes time to get converted into glucose and released into the blood again.
table
When sucrose is processed, it is bleached and crystalized -- resulting in what is commonly known as "__________ sugar" - which lacks any vitamins and minerals that are found in unprocessed sugar cane and beets.
