Terms 2 Flashcards
Protein
Large biomolecules or macromolecules consisting of one or more long chains of amino acid residues. Does most of the work in cells required for the structure function and regulation of the bodies tissues and organs.consist of eight essential and 12 nonessential amino acids.
Lipids
Store energy, signal and act as structural components of cell membranes. Molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells; a group of naturally occurring molecules that includes fats, waxes sterols and fat soluble vitamins (vitamins A, D, E, K) monoglycerides, diglycerides, triglycerides, phospholipids.
Triglycerides
Main constituents of natural fats and oils. High concentrations in the blood indicate elevated risk of stroke. 9 calories per gram - most concentrated source of energy in diet.
Water-Soluble Vitamins
Can dissolve in water. Carried to the body’s tissues but not stored in the body. Found in plant and animal foods or dietary supplements and must be taken daily. Vitamin C and B.
Fat-soluble vitamins
Vitamins that are soluble in fats or lipids, usually absorbed in fat globules that travel through the lymphatic system of small intestine and into general blood circulation within body. Stored in body tissues. Vitamins a and E.
RDA of sodium
Recommended dietary allowance for sodium is average intake level of what you should be getting from your diet daily. No more than 2300 mg daily or 1500 if you’re older than 51 or black or have high blood pressure, diabetes or chronic kidney disease
Amino Acids
Create protein molecules. Eight essential provided by diet, 12 nonessential synthesized by body. All 20 required for proper nutrition
Basal metabolism
Minimum amount of energy required by body to maintain essential body functions (temperature, muscle tone, respiration)
Cholesterol
A compound of the sterol type found in most body tissues, including blood and nerves. Important constituent of cell membranes. High concentrations in blood promote atherosclerosis
Glycogen
Polysaccharide that is principal storage form of glucose in cells
Incomplete Proteins
Low or lacking in one or more of the amino acid needed to build cells. Found in plant foods and can be mixed together to make a complete protein
HDL LDL recommended levels
HDL should be above 40 for men and above 50 women; above 60 is excellent. LDL should be less than 130.
Trans Fats
A type of unsaturated fat. Created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. Commonly found in processed food and labeled as partially hydrogenated oil.
Saturated Fats
Saturated with hydrogen atoms. The more saturated it is the more solid it is at room temperature.
Unsaturated Fats
Missing hydrogen atoms. Less solid at room temp. Omega-3 and omega-6
