The present invention relates to a process on a large industrial scale for the production of thylakoids, from photosynthetic organisms, such as from green plant leaf material, to be used as ingredients in food, or additions to food, or dietary supplements, or pharmaceuticals for the purpose of preventing overweight, promoting satiety, reducing food intake, reducing bodyweight, reducing blood insulin concentration and reducing blood fats and percentage body fat in humans and animals.

TGD2 proteins of Arabidopsis are proposed to be a substrate binding component of a lipid transfer complex in the inner chloroplast envelope membrane. Loss of function of this protein or other components of this complex may disrupt the endoplasmic reticulum (ER)-pathway of thylakoid lipid biosynthesis. In one embodiment, the present invention contemplates a minimal binding domain capable of specifically binding phosphatidic acid. Alternatively, the minimal binding domain may further comprise accessory binding domains that, in combination, create a complete TGD2 phosphatidic acid binding domain. Consequently, phosphatidic acid may be quantitatively detected from samples as described in the methods herein.

The invention relates to a method for preparing a nanometer light adsorption material based on a plant thylakoid structure, belonging to the technical field of nanometer semiconductors.
