What reactions break down triglycerides?
Lipolysis. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm.
What type of reaction breaks the bonds in a triglyceride?
Hydrolysis Reaction Triglycerides, like other molecules possessing ester groups, are able to undergo hydrolysis. Hydrolysis is a type of chemical reaction where a water molecule breaks a bond.
Where are lipids broken down?
small intestine
The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases. The mouth and stomach play a small role in this process, but most enzymatic digestion of lipids happens in the small intestine.
Which enzyme breaks down triglycerides into glycerol and fatty acids?
lipase
lipase, any of a group of fat-splitting enzymes found in the blood, gastric juices, pancreatic secretions, intestinal juices, and adipose tissues. Lipases hydrolyze triglycerides (fats) into their component fatty acid and glycerol molecules.
What is saponification give example?
Saponification is the hydrolysis of an ester under acidic or basic conditions to form an alcohol and the salt of a carboxylic acid. Saponification is commonly used to refer to the reaction of a metallic alkali (base) with a fat or oil to form soap. Example: Ethanoic acid reacts with alcohols in the presence of a conc.
Are triglycerides liquid?
Many vegetable triglycerides (oils) are liquid at room temperature, unlike those of animals; in addition, they contain a greater variety of fatty acids. In alkali, triglycerides are broken down (saponified) to form glycerol and three molecules of soap (salts of the fatty acids).
What enzymes are responsible for the breakdown and digestion of triglycerides quizlet?
The enzyme gastric lipase, secreted in the stomach, begins the digestion of some triglycerides. The most common fat in foods are made up of three fatty acids attached to a three-carbon glycerol backbone and are called triglycerides.
What enzyme break down carbohydrates?
Saliva releases an enzyme called amylase, which begins the breakdown process of the sugars in the carbohydrates you’re eating.
