Document Summary
Plants: glycogen starch (amylopectin and amylose) & fibre. Glycoprotein: covalent link between protein and a carbohydrate monomer. Oligosaccharides: 3-9 cho monomers: considered to be a complex carbohydrate. Examples: raffinose: galactose, glucose, and fructose, stachyose: 2 galactose, glucose, fructose, found in dry beans, peas, lentils, fermentation. Tubers: potatoes, yams, cassava (toxic in raw form) Examine examples of nutritional values of similar types of complex carbohydrates. So, why do we need to eat carbohydrates: energy needs. Fuel source for neurons (only uses glucose except during starvation . can uptake protein. Need cho to metabolize other fuels fat burns in a flame of carbohydrates : pregnancy: fetus and placenta feed on glucose. Gestational diabetes: elevated blood glucose during pregnancy: spares muscle protein degradation for energy. Glucose must be synthesized from muscle protein. Amino acids converted to: (1) ketone bodies, (2) fatty acids, (3) glucose. Major source of production is the liver (inside mitochondrion) Heart and renal cortex cells: ketone bodies are used as fuel.
